The Highline Forum held its July 22, 2020 meeting virtually via Microsoft Teams, hosted by the City of Federal Way, focusing on ultra-fine particle studies, noise program updates, and StART (Sea-Tac Airport Roundtable) developments near Seattle-Tacoma International Airport. Key presentations included University of Washington air quality research (MOV-UP study), a temporary noise monitors update from the Port of Seattle, and a South King County Fund update. The meeting was conducted remotely due to the Governor's Stay-at-Home Order, with public comments accepted via email or MS Teams.

Researchers at the University of Washington conducted the MOV-UP study to measure ultrafine particle (UFP) pollution around Seattle-Tacoma International Airport and the neighborhoods affected by its air traffic. The study aimed to determine how much of the UFP exposure in surrounding communities comes specifically from jet aircraft, which emit extremely tiny particles (under 30 nanometers) along flight paths, versus other sources like diesel vehicles on nearby roads. Findings and community feedback were shared with local governments to inform air quality and noise policy decisions.

A 2019 University of Washington study found that communities within 10 miles of Seattle-Tacoma International Airport are exposed to ultrafine particle pollution uniquely linked to aircraft emissions, distinct from roadway traffic pollution. These microscopic particles — 700 times thinner than a human hair — are not currently regulated by federal or state air-quality standards, and prior research has associated them with breast cancer, heart disease, prostate cancer, and lung conditions. The policy brief calls on Washington State legislators to fund a follow-up two-year study to investigate the health impacts on nearby communities, which tend to be poorer and more racially diverse than King County as a whole.

The Burien Airport Committee met on December 17, 2019 to discuss ongoing concerns related to Sea-Tac Airport, including the city's legal findings against the FAA, the status of a University of Washington ultrafine particles study, and safety issues raised by Alaska Airlines and Horizon Air. The committee also reviewed progress on the Sea-Tac Stakeholder Advisory Round Table (StART) and a Washington State Department of Commerce study, while planning priorities for 2020. Draft minutes from the November 18, 2019 meeting were included, detailing earlier discussions on noise reduction, environmental impacts, and a potential meeting with the EPA.

The Burien Airport Committee met on May 21, 2019 to discuss several airport-related issues, including updates on the Sea-Tac Airport Master Plan (SAMP) environmental review process, the formation of a coalition of local elected officials to address airport concerns, and research into noise mitigation programs such as the Sound Insulation Program. The committee also reviewed a Federal Way letter to University of Washington professors regarding a study on ultrafine particle pollution from aircraft, and discussed Burien's ongoing participation in the Sea-Tac Airport Roundtable (StART). Draft minutes from the April 16, 2019 meeting reflect earlier discussions on flight curfews, landing fee structures, and airport governance as potential tools for reducing noise impacts on surrounding communities.
